Review on 🚴 Stay Hydrated on Your Bike: CamelBak Hydrobak Light Bike Hydration Pack 50oz by Jake Meyer

Bought these for my kids when we went to the mouse house, yes they can be "expensive" but they did their job and at WDW in September it did a great job well done, highs were ice/water/gatorade filled in the mid 90's, stayed cool through noon, others may complain that it doesn't stay cool and they are right to an extent, water in the blue hose has none Insulation so those 3-4 oz won't be there Regardless of the temperature outside, keep drinking and you'll get cooler bubble water in the bag. The kids have worn them all day with no complaints except they have their own water on request. You could also fit a poncho, applesauce pomace and 2 granola bars and the wallet in a pocket compartment with room for extras - not only useful for trips to the amusement park but for using z only for that it worked great!
